Thanks for a swift response.
We are using 10.2.10.
They all share the same set of permissions (and one key, too). Haven't
found anything incriminating in logs, too.
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx
pool=rbd
Are you sure you pasted correct user permissions? It looks like you are
using RBD permissions for CephFS and this seems to be the problem.

Hi,
we've recently hit a problem in a production cluster. The gist
of it is that sometimes file will be changed on one machine,
but only the "change time" would propagate to others. The
checksum is different. Contents, obviously, differ as well.
How can I debug this?
In other words, how would I approach such problem with "stuck
files"? Haven't found anything on Google or troubleshooting docs.
What versions are you running?
The only way I can think of this happening is if one of the
clients had permission to access the CephFS namespace on the MDS,
but not to write to the OSDs which store the file data. Have you
checked that the clients all have the same caps? ("ceph auth list"
or one of the related more-specific commands will let you compare.)
